[uClibc] Problems with uclibc toolchain and c++

[Bohman, Mikael]

Hello,

I'm using the gcc-3.3.1 toolchain from cvs with uclibc 0.9.21 to compile c++ for a i386 target. My problem is that dynamically linked applications exits with a SIGABRT when I throw an exception. If I link statically everything works fine. 

This is my test program:

#include <stdexcept>
int main(int argc, char* argv[])
{
    try
    {
        throw std::exception();
    }
    catch (const std::exception &e)
    {
    }

    return 0;
}

The stack trace looks like this:

#0  0x400b9fe8 in kill (pid=1074542516, sig=6) at syscalls.c:463
#1  0x400b4906 in raise (signo=6) at raise.c:12

#6  0x08048657 in main (argc=1, argv=0xbffffed4) at test.cpp:7

Has anyone else seen this?
